![]() ![]() In a game, points were won and lost, represented by integers. 1.įind the range of these distances run by 6 marathon runners:įind the range of these race times given in seconds:ħ.3 s, 8.4 s, 8.0 s, 7.5 s, 9.4 s, 8.7 s, 9.1 sĮmployees at a retail store are paid the hourly wages listed below. After you click ENTER, a message will appear in the RESULTS BOX to indicate whether your answer is correct or incorrect. Then subtract the smallest value from the largest value in the set.ĭirections: Click once in an ANSWER BOX and type in your answer then click ENTER. Range, which is the difference between the largest and smallest value in the data set, describes how well the central tendency represents the data. ![]() To find it, first order the data from least to greatest. Summary: The range of a set of data is the difference between the highest and lowest values in the set. Highest - lowest = 8.3 hr - 2.7 hr = 5.6 hr Example Ritchie earned the following scores in his gymnastics events: The greatest number is 9.7 The smallest number is 9. What is the range of times given in hours below? Highest - lowest = 19 -12 = 19 + +12 = +31Įxample 3: A marathon race was completed by 5 participants. The range is a mathematical tool thats used in finding the spread in a data set. Yes - that is how it works, if you have f (x)x² and are asked what is f (2), then you replace every instance of x in the function definition with 2 so given f (x) x², that means f (2) 2² 4. Kaiser listed 9 integers on the blackboard. Solution: Ordering the data from least to greatest, we get:Įxample 2: Ms. It is the difference between the largest and smallest numbers. Gasoline prices varied from state to state. Range tells how far apart the greatest and least numbers in a set are. that would not cause us to attempt an undefined mathematical operation. Let's take a closer look.Įxample 1: The Jaeger family drove through 6 midwestern states on their summer vacation. For example, the domain and range of the cube root function are both the set of. In other sciences, this set is also called the input. The first group, the domain, is the set of x variables in the function. This is especially important with large sets of data. 1: Mapping or pairing up of two sets showing a function behavior. In the examples below, our first step is to order the data from least to greatest. ![]() Definition: The range of a set of data is the difference between the highest and lowest values in the set. ![]()
